This patch is a port of the work by Sudhakar Rajeshekhara in commit ab3effbcad8851cc65dc5241a01c064d2030a3b2 of git://arago-project.org/git/people/sandeep/u-boot-davinci.git. The da850 UI board has on it an RMII PHY which can be used if the MDC line to the MII PHY on the baseboard is disabled and the RMII PHY is enabled by configuring the values of some GPIO pins on the IO expander of the UI board. This patch implements disabling that line via GPIO2[6], configuring the UI board's IO expander and setting only the pinmux settings that are needed for RMII operation. Tested on da850evm by adding a define for CONFIG_DRIVER_TI_EMAC_USE_RMII.
